The Angels were down 2-1 when Richards exited. Noe Ramirez came on in relief to start the bottom of the third inning.

Richards threw 35 pitches, but saw a dip in velocity during his outing. He has averaged 96.5 mph on his fastball this season but averaged only 94.8 mph Wednesday, according to MLB.com.

Injuries are not new for Richards, who missed most of the 2016 season with an arm injury although he did avoid Tommy John surgery. He returned in 2017, but was limited to six starts due to nerve irritation in his right biceps.
